Hello @YOSHIE. I am Robicrypto and my ETH address is 0x637434A754A4704a75F0fa06047264f1953996a3. I haven't any alternative account. @donatello345 just copied my proof of authentication post and forgot to edit the ETH address. You can search my ETH address on forum. ETH address of @donatello345 is
 0xc7d34E2d1F97DB2800827C58Dc344FFa89aaCb55.



@donatello345 use my ETH address just on the proof post of Grandle campaign. But in the Grandle spreadsheet, he use his own ETH address. You can check twitter spreadsheet no 605.
